The Department of Water and Environmental Regulation uses groundwater models to inform groundwater resource management across the State.
The Perth Regional Aquifer Modelling System (PRAMS) is a dynamically coupled recharge and groundwater flow model for the Perth metropolitan area. Its primary objective is to predict the impacts of groundwater abstraction, climate and land-use changes on a range of environmental and community assets throughout the region.
In July 2024, PRAMS was updated to version 3.6. The update extended the history matching period to 2019 and used industry leading, automated parameter estimation techniques. This allowed a significant increase to model parameterisation and resulted in the best model fit to observed data seen so far in PRAMS.
